three-time gold medalist kristin armstrong, and everyone has seen those beautiful moments with your son after your win. he's 5 years old and he's like, momma, why are you crying? the pictures tell a lot. tell me what you were feeling and thinking in those moments. >> those moments when you cross the finish line, you go through a lot of emotions within what feels like ten minutes but it's probably within like a minute and i went from exhaustion, joy and i saw my son and started just crying, and when i went over for that hug, he in my ears said, momma, why are you crying? and there was a pause, and he said, didn't you win? and i said, yeah, i did. he goes, then why are you crying? and so i thought of it as just another life lesson to teach because at age 5, you don't quite understand that joy and happiness and being overwhelmed can also bring tears. >> yeah, no, it was such a beautiful moment to watch. also happy birthday. >> oh, thank you. >> welcome to 43. we're the same age, babe.
